“…However, the high bond strength of Transbond Plus Self Etching Primer did not stem from its high acidity, as it was recently demonstrated that the pH value of self-etching adhesives is not a primary determinant of SBS 24) . As for Transbond XT, the high bond strength it produced was probably due to the higher consistency of its adhesive paste as compared to other flowable composites.…”

This study evaluated the shear bond strengths of orthodontic brackets bonded to human premolars using five different combinations of flowable composites and one-step self-etching adhesives (n=12): (1) Adper Easy Bond+Filtek Supreme XT Flow; (2) Futurabond NR+Grandio Flow; (3) Clearfil S3 Bond+Clearfil Majesty Flow; (4) AdheSE One+Tetric EvoFlow; and (5) Transbond Plus Self Etching Primer+Transbond XT Light Cure Adhesive. After shear bond strength testing, adhesive remnant index (ARI) scores were given according to the amount of adhesive and resin remaining on the brackets. On shear bond strength, there were no statistically significant differences between Groups 2 and 4 and between Groups 3 and 5 (p>0.05). On ARI scores, the predominant ARI scores in Groups 1, 2, 3, and 5 were 4, 2, 5, and 4 respectively; in Group 4, they were 0 and 4. Results showed that some combinations of flowable composites and self-etching adhesives might not be suitable for orthodontic use due to their low shear bond strengths and high ARI scores -with the latter signaling the risk of damaging the enamel surface during debonding.

“…9,11 It has also been concluded that SEPs that produce a minimal etch pattern can still provide adequate bracket SBS. 12 Additionally, it was observed that when using a self-etching adhesive to bond brackets, no significant difference was seen when the SEP was cured either in separate steps or simultaneously with the bonding adhesive. 13 A new self-etching adhesive, AdheSE One (Ivoclar Vivadent Inc, Amherst, NY), was introduced for use in operative dentistry.…”

“…14 Although marketed for use in operative dentistry, it has been demonstrated that other restorative-based selfetching systems have been used successfully to bond orthodontic brackets. 12,13 Unlike most self-etching systems, the AdheSE One offers the advantage of not having to be mixed prior to application. This in turn may reduce technique sensitivity by eliminating the chance of improper mixing and the resulting inadequate SEP activation.…”

Objective: To determine if a new premixed self-etch adhesive can be used to successfully bond orthodontic brackets to enamel. Materials and Methods: Forty human molars were cleaned, mounted, and randomly divided into two groups. In group 1, 20 teeth were conditioned using the self-etching primer Transbond Plus (3M Unitek, Monrovia, Calif). In group 2, 20 teeth were conditioned using a new premixed selfetching adhesive, AdheSE One (Ivoclar Vivadent Inc, Amherst, NY). Both groups were bonded using brackets precoated with a composite adhesive. The teeth were debonded within half an hour following initial bonding using a universal testing machine. After debonding, the enamel surface was examined under 10ϫ magnifications to determine the amount of residual adhesive remaining on the tooth. A Student's t-test was used to compare the shear bond strength (SBS) of the two groups, and the Chi-square test was used to compare the adhesive remnant index (ARI) scores for the two adhesive systems. Results:The mean SBS of the brackets bonded to the teeth using AdhesSE One was 3.6 Ϯ 1.3 MPa and was significantly lower (t ϭ 2.80, P ϭ .01) than the SBS of the brackets bonded using Transbond Plus (x ϭ 5.9 Ϯ 3.2 MPa). The comparisons of the ARI scores between the two groups ( 2 ϭ 19.26) indicated that bracket failure mode was also significantly different (P Ͻ .001), with more adhesive remaining on the teeth bonded using Transbond Plus. Conclusions: The SBS of the new premixed self-etching adhesive needs to be increased for it to be successfully used for bonding orthodontic brackets.

“…4,5 While these advantages lead many clinicians to adopt SEPs, bond strengths comparable to those offered by traditional etching and priming are critical for clinical use, 1,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] so the application method of SEPs warrants further investigation. 14 The application technique, a combination of time and agitation (rubbing), has been studied for Transbond Plus (3M Unitek, Monrovia, Calif), a popular orthodontic self-etching system.…”

Objective: To test the manufacturer's recommendation for the application rubbing time of a selfetching primer (Transbond Plus, 3M Unitek) and to compare the resulting bond strength of a resin composite (Transbond XT, 3M Unitek) in the traditional laboratory tension on all four wings with a simulation of the clinical single-wing lift-off debonding instrument (LODI; 3M Unitek). Materials and Methods: Flattened stainless-steel maxillary incisor orthodontic brackets (Victory Series, 3M Unitek) were bonded to 108 flattened bovine incisors. The enamel was rubbed with the self-etching primer for 0, 5 (the manufacturer's recommendation), and 10 seconds during a 10-second application. Traditional four-wing and LODI simulated debonding forces and the adhesive remnant index (ARI) were recorded. Results: One-way analysis of variance testing among rubbing times and debonding methods indicated a significant difference in strength with 0 and 5 seconds of rubbing and between traditional and LODI simulated tension. The bond strengths were higher in the ARI 5 1 subset compared to the ARI 5 3-5 subsets. Conclusions: The manufacturer's recommendation for primer rubbing time produced the highest bond strength. Less force is required for debonding when tension is applied to one wing (LODI simulation) vs on all four wings. (Angle Orthod. 2012;82:131-136.)
